πŸ”— Louis Le Prince, the missing inventor of an early motion-picture camera

πŸ”— Biography πŸ”— France πŸ”— Biography/science and academia πŸ”— Biography/Actors and Filmmakers

Louis AimΓ© Augustin Le Prince (28 August 1841 – disappeared 16 September 1890, declared dead 16 September 1897) was a French artist and the inventor of an early motion-picture camera, possibly the first person to shoot a moving picture sequence using a single lens camera and a strip of (paper) film. He has been credited as the "Father of Cinematography", but his work did not influence the commercial development of cinemaβ€”owing at least in part to the great secrecy surrounding it.

A Frenchman who also worked in the United Kingdom and the United States, Le Prince's motion-picture experiments culminated in 1888 in Leeds, England. In October of that year, he filmed moving-picture sequences of family members in Roundhay Garden and his son playing the accordion, using his single-lens camera and Eastman's paper negative film. At some point in the following eighteen months he also made a film of Leeds Bridge. This work may have been slightly in advance of the inventions of contemporaneous moving-picture pioneers, such as the British inventors William Friese-Greene and Wordsworth Donisthorpe, and was years in advance of that of Auguste and Louis Lumière and William Kennedy Dickson (who did the moving image work for Thomas Edison).

Le Prince was never able to perform a planned public demonstration of his camera in the US because he mysteriously vanished; he was last known to be boarding a train on 16 September 1890. Multiple conspiracy theories have emerged about the reason for his disappearance, including: a murder set up by Edison, secret homosexuality, disappearance in order to start a new life, suicide because of heavy debts and failing experiments, and a murder by his brother over their mother's will. No conclusive evidence exists for any of these theories. In 2004, a police archive in Paris was found to contain a photograph of a drowned man bearing a strong resemblance to Le Prince who was discovered in the Seine just after the time of his disappearance, but it has been claimed that the body was too short to be Le Prince.

In early 1890, Edison workers had begun experimenting with using a strip of celluloid film to capture moving images. The first public results of these experiments were shown in May 1891. However, Le Prince's widow and son Adolphe were keen to advance Louis's cause as the inventor of cinematography. In 1898, Adolphe appeared as a witness for the defence in a court case brought by Edison against the American Mutoscope Company. This suit claimed that Edison was the first and sole inventor of cinematography, and thus entitled to royalties for the use of the process. Adolphe was involved in the case but was not allowed to present his father's two cameras as evidence, although films shot with cameras built according to his father's patent were presented. Eventually the court ruled in favour of Edison. A year later that ruling was overturned, but Edison then reissued his patents and succeeded in controlling the US film industry for many years.

πŸ”— Fairfax, California B-17 Crash in 1946

πŸ”— California

Early on the morning of May 16, 1946, a U.S. Army B-17 Flying Fortress aircraft crashed into White's Hill (also known locally as "White Hill") near Fairfax, California. Two men were killed and six seriously injured. There were reports that the B-17 was carrying nuclear weapons materials for the Operation Crossroads tests at Bikini atoll, but these reports were not confirmed. However, due to the behavior and activities of the military authorities at the crash site and the reports of several credible witnesses, including several of the crewmembers, questions about the plane's cargo remain.

πŸ”— Werckmeister Temperment

Werckmeister temperaments are the tuning systems described by Andreas Werckmeister in his writings. The tuning systems are numbered in two different ways: the first refers to the order in which they were presented as "good temperaments" in Werckmeister's 1691 treatise, the second to their labelling on his monochord. The monochord labels start from III since just intonation is labelled I and quarter-comma meantone is labelled II. The temperament commonly known as "Werckmeister III" is referred to in this article as "Werckmeister I (III)".

The tunings I (III), II (IV) and III (V) were presented graphically by a cycle of fifths and a list of major thirds, giving the temperament of each in fractions of a comma. Werckmeister used the organbuilder's notation of ^ for a downwards tempered or narrowed interval and v for an upward tempered or widened one. (This appears counterintuitive - it is based on the use of a conical tuning tool which would reshape the ends of the pipes.) A pure fifth is simply a dash. Werckmeister was not explicit about whether the syntonic comma or Pythagorean comma was meant: the difference between them, the so-called schisma, is almost inaudible and he stated that it could be divided up among the fifths.

The last "Septenarius" tuning was not conceived in terms of fractions of a comma, despite some modern authors' attempts to approximate it by some such method. Instead, Werckmeister gave the string lengths on the monochord directly, and from that calculated how each fifth ought to be tempered.

πŸ”— Fuzzy Logic

πŸ”— Mathematics πŸ”— Philosophy πŸ”— Statistics

Fuzzy logic is a form of many-valued logic in which the truth values of variables may be any real number between 0 and 1 both inclusive. It is employed to handle the concept of partial truth, where the truth value may range between completely true and completely false. By contrast, in Boolean logic, the truth values of variables may only be the integer values 0 or 1.

The term fuzzy logic was introduced with the 1965 proposal of fuzzy set theory by Lotfi Zadeh. Fuzzy logic had, however, been studied since the 1920s, as infinite-valued logicβ€”notably by Łukasiewicz and Tarski.

Fuzzy logic is based on the observation that people make decisions based on imprecise and non-numerical information. Fuzzy models or sets are mathematical means of representing vagueness and imprecise information (hence the term fuzzy). These models have the capability of recognising, representing, manipulating, interpreting, and utilising data and information that are vague and lack certainty.

Fuzzy logic has been applied to many fields, from control theory to artificial intelligence.

πŸ”— Daughter from California Syndrome

πŸ”— Medicine πŸ”— Death πŸ”— Medicine/Society and Medicine

"Daughter from California" syndrome is a phrase used in the medical profession to describe a situation in which a long-lost relative arrives at the hospital at which a dying elderly relative is being treated, and insists that the medical team pursue aggressive measures to prolong the patient's life, or otherwise challenges the care the patient is being given. In his 2015 book The Conversation: A Revolutionary Plan for End-of-Life Care, American doctor Angelo Volandes ascribes this to "guilt and denial," "not necessarily what is best for the patient."

The "daughter from California" is often described as angry, articulate and informed.

Medical professionals say that because the "daughter from California" has been absent from the life and care of the elderly patient, they are frequently surprised by the scale of the patient's deterioration, and may have unrealistic expectations about what is medically feasible. They may feel guilty about having been absent, and may therefore feel motivated to reassert their role as an involved caregiver.

The phrase was first documented by a collective of gerontologists in a 1991 case report published in the Journal of the American Geriatrics Society, titled "Decision Making in the Incompetent Elderly: 'The Daughter from California Syndrome'". In the paper, Molloy and colleagues presented strategies intended to help medical staff deal with the difficult family members of mentally incompetent patients.

In California, the "daughter from California" is known as the "daughter from New York".
